Embryo quality related to its developmental potential is now one of the most important issues
in modern embryology. It has been demonstrated that some in vitro produced blastocysts fail …

Human disease is rarely a matter of all or nothing; variable expressivity is generally
observed. Part of this variability is explained by somatic mosaicism, which can arise by a …

Mammalian preimplantation embryonic development is achieved by tightly coordinated
regulation of a great variety of temporal and spatial changes. Therefore, it would be valuable …

Somatic cell nuclear transfer (scNT) is a useful way to create cloned animals. However,
scNT clones exhibit high levels of phenotypic instability. This instability may be due to …

Objective In this review, we focus on the possible relationship between telomere dysfunction
and aneuploidy in human early embryo development and several reproductive and perinatal …

Embryo genomic selection (preimplantation genetic screening) is increasingly being used to
select the best embryos within cattle breeding programs. The procedure starts with the …

Background Somatic cell nuclear transfer (SCNT) provides an appealing alternative for the
preservation of genetic material in non-domestic and endangered species. An important …

Somatic cell nuclear transfer (SCNT) can provide a unique alternative for the preservation of
valuable individuals, breeds and species. However, with the exception of a handful of …

Chromosomal aberrations are one of the major causes of embryo developmental failures in
mammals. The occurrence of these types of abnormalities is higher in in vitro-produced (IVP) …

The aim of this study was to assess the following parameters in prepubertal goat oocytes of
different follicle diameter (≥ 3 mm,< 3 mm, control): oocyte diameter, early (Annexin-V) and …
